17 What has the hdd temp to do with cpu tmeprature?

22 Reboot quickly (Alt-SysRq-S, Alt-SysRq-U, Alt-SysRq-B to do this really fast
23 when the Magic SysRq feature is build into the kernel) and check the
24 temperature in the BIOS.
25
26 To monitor it with Linux runing, emerge sys-apps/lm_sensors. A howto like
27 http://gentoo-wiki.com/HARDWARE_Sensors might be of help when configuring.
